Re: [racket-users] Custom command completion?

[Sam Tobin-Hochstadt]

Right now, `raco` doesn't have anything like that, for either built-in
or custom commands. What there is currently is this code:
https://github.com/racket/shell-completion which basically hard-codes
options, and calls `racket` to complete `raco` commands. It knows
specifically about `raco planet` so that it can complete for that.

You could write something that used `get-info` to get the relevant
information from a spec like you describe there, and add it to that
code. A warning: those completion scripts start slower than I'd like
when I use them, because of Racket's startup time.

Right, but shell completion varies by shell implementaiton so I was hoping that 
raco
would have some built-in completion script that racket installs, and that 
script would
dispatch to some racket code that implements custom completion for a particular 
command
I'd like to stick something like this in an info.rkt file:

(define raco-commands
  '(("some-command" command-impl-mod "Some command" 20 #:complete-with 
(completion-impl-mod completion-procedure-binding

...and have `raco` setup a single completion script on installation that 
notices when you're
completing a command with custom completion and dispatches to it. That way I 
don't have
to figure out how to get raco pkg install to put shell scripts in the right 
places.

Shell completion (at least for bash, which I know best) isn't handled
by `raco` at all -- it's all done in bash. So I think you'd have to do
some shell script hacking.

[racket-users] Custom command completion?

[Jack Firth]

If I have a `raco` command that I want to add command completion too, how can I 
do that?
Ideally I'm looking for some way to tell raco to dispatch to a particular 
function whenever
shell completion is requested for any uses of my raco command. If there is no 
way to do this
right now, what would I need to build for it?
